Ensure product stability and sustainability with HotSpot automated quality control

HotSpot is a fully automated thermal vision inspection system that eliminates defects in packaging and avoids expensive product recalls. HotSpot stops faulty packaging in its tracks. Make plastic wrap a thing of the past by guaranteeing your cardboard or paperboard packaging is strong, safe, and sturdy. 

This fully automated quality control inspection system accurately and instantly checks hotmelt glue adhesive across a wide variety of packaging types. HotSpot helps industries phase out single-use plastics and can be retrofitted to existing packaging lines.

Combining FLIR thermal cameras with Cognex Vision Pro software, HotSpot can monitor the shape, size, location, and temperature of hotmelt glue application to ensure packaging is correctly formed and sealed.

How it works

Cartons are formed then hot melt glue is applied to the carton flaps. The flaps are then folded and sealed to the carton sides to complete the assembly. By measuring that the glue is at the required temperature, has been applied to the correct area and in the desired quantity, you can be assured that the carton will not fail and is safe to be transported. Missing glue means potential breakages in logistics or at the point of sale. Badly shaped cartons means poor product sales.

The HotSpot vision system consists of a colour camera and FLIR LWIR camera, inspecting the areas where the flaps are sealed. The thermal imaging camera is providing a measurement of the glue temperature and location, through the carton material. The colour camera checks that the flaps have been properly formed and that the carton is of the correct shape. If HotSpot identifies a failure from either camera, the system can provide a digital output to the production line.
